Effectiveness of a media literacy-based smoking prevention program in female adolescents

To examine the effectiveness of a media literacy-based smoking prevention program based on Ajzen's theory of planned behavior in female adolescents.

This quasi-experimental study was conducted with female high school students aged 16-17 years in Seoul, Republic of Korea. The program provided eight sessions over 4 weeks. Quantitative data were collected before and after online surveys in an intervention (n = 21) and control (n = 21) groups, and analyzed using mixed analysis of variance. Qualitative data on participation experiences was collected by requesting the participants to answer open-ended questions once a week during the intervention and performing co-occurrence analysis of specific terms in the responses was conducted through text mining.

Although the program decreased smoking intention and increased smoking media literacy in the intervention group, there were no significant differences between the groups. Qualitative results obtained from the intervention group showed cognitive and behavioral changes in the perception of the harmfulness of e-cigarettes in the media and the expression of a willingness to overcome the temptation to smoke.

Our findings show that the enhancement of smoking media literacy, specifically by correcting misconceptions regarding e-cigarettes promoted by the new media, contributes smoking prevention in female adolescents. It supports calls for an expanded role of public health professionals in health education at the school level.
